A genuine Audi radiator coolant hose grommet (OEM 4K0121585E) is a small but essential seal that prevents coolant leaks where the hose connects to the engine or radiator. Used on 2.0L TFSI, 2.9L, and 3.0L turbocharged and MHEV engines from the A6, S6, and S7, this grommet can crack over time, leading to dripping coolant and potential overheating. Replacing a worn grommet restores a tight, leak-free seal without replacing the entire hose.
